LOCOMOTIVE-TENDEB.

To all whom it may concern:

Be it known that I, EDWARD RYAN, a citizen' of the United States, and resident of Chicago, county of Cook, and State of lllinols, have invented certain new and useful Improvements in Locomotive-Tenders, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

e invention relates to a locomotive power mechanism for advancing the fuel The objects of the invention are t'oprovide for a simple and comparatively. inexpensivearrangement of the fuel advancing mechanism and tender walls, to protect the power mechanism of the fuel-advancing means against injury in loading and with trespassing upon the capacity tank of the tender, and to gen- An embodiment of the invention is hereinafter described, and is illustrated in the accompanying drawings in 'which- Figure 1- is a detail plan view of the tender, some of the parts being broken awa Y Fig. 2 is a detail central vertical section of the tender; a

F'g..3 is a sectional detail on the line o 3-3 of Fig. 2;

v Fig. 4 is a detail transverse sectional view of the tender in perspective;

I Fi 8 1s a longitudinal sectional view of the orward end of the valve mechanism. The tender 10 is of common t e, being provided at its forward end w1 bin and at its rearwardend with a water tank, the latterextendingl'lforwardly along each side and below the el bin, as shown at 11,12. f

The fuel bin is provided with the usual a slope sheet, the latter, however, in this features. I The side we 14, 15, of the fuel bin vertically from the floor 13 for a short d1safuel.

- deck.

tance and then incline outwardly, as represented at 16, 17, to the outer walls of the tender. At its rearward end the floor.

by the numeral 18, is offset upwardly, terminating a short distance above the floor v 13. The space between the two sections of the slope sheet 13 and 18 is closed, except at the central ortion, by plates 19, 20.

plate 21, s own as a continuation of the section 13 of the slope sheet, extends upwardly from the mid le portion of the latter parallel with and back of the portion 18 of the slope sheet to the top or deck plate 22 of the tank. .Wall plates, as 23, extend upwardly'from the plates 19, 20, uniting the slope sheet 18 and plate 21, thereby forming a chamber, open at its lower end for the accommodation of the'pitman connecting the motor with a pushing element. Preferably the portion of the slope sheet 18 which covers this chamber is a separate piece secured by rivets or other suitable means for. convenience in assembling.

A pusher head 24 reciprocates over the rear portion of the floor,13,and its extension 13", its ends fitting under guide flanges 25, 26, secured (to the vertical walls 14, 15, of the bin. This head 'may be provided with upwardly projecting oscillatable" leaves 27, l

which, upon the backward movement of the pusher head, fold downwardly in order 'el. The pusher head is connected to the crosssheet, by meansof a pitman 29.-

A reciprocating motor, the cylinderof which is desi ated 30, is located above the, deck 22 and back of the slope sheet 18, and ma .be I conveniently supported by means 0 brackets 31, 32, secure to vertical plates 33 34, joining the slope sheet 18 and c axis of this motor is arallel with the slope sheet, and on the median line of the central chamber therebelow, its piston rod 35 being attached to the cross-head 28. Steam for actuating the motor 1s supplied through a pipe 36 from the locomotive, which is connected with a service that they may more easily slide under the at Y y Lemma suitable valve is provided. for securingthis result. .For this purpose there is shown a s cylindrical valve 41, having an annular cavity in its periphery, and reciprocating Withm .the casing. 28, and playing over ports 42,

4 which communicate, respectlvelyf'with the distributing pipes 39, lm-exhaust ports 5:44:, so locatedas to be always between two annular faces of the valve, communieating with' an exhaust passage 45 which preferably'discharges intothe water tank of the tender. The stem 46 of this valve extends through the service pipe 37 and a stufling box 47. in'its" forward end, and. is

4 controlled by means of a suitable handle 48. The inner end of the valve stem is tubular,

. -.as shown at 49, and opens through the valve 41, vbeing ported, as shown at 50, to permit the entry of steam. ln'the normal position of the valve steam is delivered to the upper endof themotor cylinder 30, the lower end thereof being open to the ex aust. A drain so passage 51*is provided to permit the discharge of the water of condensation to the exhaust pipe from the cylinder back of the piston, when the latter is in its forward position. By this arrangement live steam is the motor cylinder at all times'andj freezing'is thereby avoided and the accumu-- lation of water in the cylinder: prevented..

, The valve 41 is so proportioned that while .it is substantially balanced, and hence easily 4O operated, there 1s a slight preponderance of tpressure at one "end resulting in its auto-- manual movement. By he construction shown and described 45 the fuel will fall by gravity from the lower "i end of the slope sheet proper upon the floor i of the bin. :When the supply of fuel upon the front portion of the floor of a the bin has been exhausted, the operator 5e shifts the valve to cause the retraction of the pusher head andthe latter slides under the mass of fuel, this movement being comparai tively easy becausethe main weight of the mass is supported by the slope sheet. The valve is again shifted, either manually or matic return to normal position, after each *by steam; pressure, to deliver steam to the, upper end-of the cylinder, thus advancing the pusher head and with it an adequate sup ply of fuel for immediate use., Any fuel which-may be carried into the chamber witha in which the pitman 29 is housed, is ejected, by the cross-head 28. The motor and its parts are well protected from being dam-- aged by the fuel when dumped into the tender bin in loading, and the motor cylinof the motive fluid for causing the advance der is shielded from the action of the weather which would have a tendency to. accelerate the condensation of steam there;

in. This protection is secured without materially encroaching. upon the tank space. At thebeginning of its forward stroke the pusher head moves'obliquely downward and travels in a curved athover the upwardlycurved rear end of t e floor plate, carrying forward the lower stratum of the fuel, the major portion of the mass beingv supported by the slope sheet 18. v I

While I have showna desirable and preferred form of construction, various changes in detail; may be made without departing from the scope of the invention.
